Description (male)
Head. Eye bridge 4–5 rows of facets. Antenna unicolour. LW-index of 4th flagellomere 1.6–1.9; neck 0.2–0.3 × segment width; transition of basal part to neck pronounced. Colour of neck unicolour. Antennal setae shorter than segment width; of normal strength; dense. Sensillae present. Antennal setae salient. Palpus darkened; of normal length; palpomeres 3. First palpomere of normal shape; with 4–5 setae; with only sparse sensilla. Second palpomere short and oval. Third palpomere as long as first. Thorax. Colour brown, or reddish. Notum unicolour. Thoracic setae long and strong; black. Posterior pronotum setose. Postpronotal setae 3; strong. Mesothoracic sclerites bare. Legs. Colour yellow. Hind coxa darkened. Setae on front coxa black. Front tibial organ as patch of setae; dark; front tibial organ not bordered. Tibial setae on hind legs normal, shorter than tibial width. Tibial spurs of equal length. Claws untoothed. Wing. Wing slightly darkened; of normal shape. Wing membrane without macrotrichia. Wing venation weak, with faint stM. M-fork of normal shape. R1 ending at or slightly before base of m-fork; posterior veins with macrotrichia; stM bare; CuA1 and CuA2 mostly with macrotrichia; bM bare; r-m mostly setose; bM:r-M 1–1.2; st-Cu:bM 0.4–0.6; R1:R 1.25–1.45; c:w 0.72–0.8. Halter darkened; of normal length. Abdomen. Abdominal setae strong; dense; on tergites black; on sternites black. Hypopygium concolour with abdomen; LW-index 0.7–0.85. Base of gonocoxites with weak setae; gonocoxites broadly separated; inner margin of gonocoxites typically U-shaped; inner membrane of hypopygium scarcely setose; ventral margin of gonocoxite with short setae. Gonostylus elongate; LW-index 2.5–2.75; Inner margin concave; apex tapered, or equally rounded. Apical tooth present; without internal structure; of medium strength; LW-Index 2–3. Awl-like setae normal; present beneath apical tooth. Megasetae absent. Whiplash-hair absent. Tegmen 0.55–0.7 × longer than broad; rectangular with rounded edges; without special features; central process absent. Length of ejaculatory apodeme/hypopygium 18–26 %; base of ejaculatory apodeme present. Field with aedeagal teeth inconspicuous. Measurements. Body size 2.5–3.2 mm. Hind tibia 1.45–1.6 mm. Wing length 2.7–3.2 mm.
Diagnosis
Trichosiopsis antimelanoma is placed in the Trichosiopsis pilosa group by the presence of short setae at the base of the gonocoxites and a not very strong apical tooth, which is partially covered by a dorsal bulge. The species is similar to Trichosiopsis melanopilosa, but has a still more tapered gonostylus. It is differing from all other species in that group by the colourful yellow legs and the nearly or completely bare m-base.
DNA Barcoding
COI sequences are assigned to the following BINs:
- BOLD:ADL1265 (n=1, K2P: 4.98%)
- BOLD:ADG6568 (n=1, K2P: 4.98%)
Etymology
The name was coined as being similar to melanoma because it is located at the opposite position in the phylogenetic clade of the melanoma complex.
Ecology
Tr. melanoma appears to be a boreo-alpine species.
Distribution
Austria, Norway.
